The Cactus Kitten 2 retained the original fuselage and engine of
the 1920 Cactus Kitten 1, but was fitted with a newly designed set
of 20 ft (6.1 m) triplane wings. In this configuration the aircraft
was entered in the 1921 Pulitzer Trophy Race. Piloted by Clarence
Coombs the aircraft placed second, with an average speed of 170.3
mph (274 kmh). At sea level the aircraft had a top speed of 196 mph
(315 kmh). Built for S.E.J. Cox from Garden City, Texas, USA, the
aircraft was sold by Cox to the US Navy for one dollar and used as
a trainer by the US Navy team for the 1922 Pulitzer Trophy Race.
